I red a lot of 5 stars reviews and bought Sony WF-1000XM4. And very disappointed with sound quality (flat, muddy, low volume) and fit (it will fall out eventually). I had previous version XM3 and sound was a lot better as well as fit. My Jabra 75t sound better even more bass. That Sony sound similar to AirPods Pro (which is nothing special but better fit than Sony). Case is smaller than XM3 but cover is very flimsy. Only 3 ear gels included vs 8 with XM3. Will return Sony XM4.
I travel via Airplane a couple of times a week for my job. The drone of the engines made it difficult to enjoy music or movies while in flight. After trying several less expensive Earbuds with no success I decided to give the SONY Wf-1000xm4 a try. Wow what a huge difference. Some engine noise can still be heard but very little. I don't have to crank the volume up in order to hear the fine details of whatever I'm listening to. This is vital if you care about not losing your hearing in the long run. Can't recommend these enough!!!
What a great improvement! I like the XM-4’s much better. The noise cancellation is so much better and they are more coming in the ears…especially with the memory foam tips.
